Junction Triangle Community Group on Facebook - Request to join denied and now blocked?

About 2 weeks ago I had requested to join the Junction Triangle Community Group on Facebook (https://www.facebook.com/groups/JTParents). A week goes by, and nothing. Checked the group again, and the pending request was no longer there. So I requested to join again, and now it seems I have been blocked from the group. I do not have a "spammer" profile, so I am curious as to why my request was not accepted. Granted I do not have any mutual friends that are part of this group, but I thought that any member can approve membership requests. Do I have to be a parent to join this group? In the description it says the group's focus is on parenting but it does not say one has to be a parent to join. I am a resident in the JT, but not a parent. Is that the reason my request was denied?
